The films will all be available for FX's various networks (FX, FXX and FXM) by mid-to-late 2015. FX execs were particularly pleased with the purchase of Despicable Me 2, as animated features work well for cable networks during the holidays.

Despicable Me 2 has already grossed $143 million at the U.S. box office during the long five-day holiday weekend. The sequel scored one of the best openings ever for an animated film.

After three weeks, World War Z has pulled in nearly $160 million domestically, while The Heat's two-week tally is $86 million. And while White House Down is a box office disappointment (just $50 million after two weeks), FX execs believe the feature will attract TV audiences that missed it in theaters.

The buys also represent a vast cross-section of movie types, and come from a wide variety of studios: Universal (Despicable Me 2), 20th Century Fox (The Heat), Paramount (World War Z) and Sony (White House Down).

FX has been busy grabbing many of this summer's most high-profile films, having previously nabbed Man of Steel, Fast & Furious 6, Star Trek Into Darkness, The Purge, This is The End, The Internship, Epic, Iron Man 3 and Pain and Gain.
